Nick and Kevin Jonas are congratulating their fellow Jonas brother on his engagement to Game of Thrones star Sophie Turner. A source tells Us Weekly that Joe Jonas, 28, and the 21-year-old Turner, who have been dating since late last year, "are madly in love." "She's young but mature and comes from a small English town, so it's not that out of the ordinary and age doesn't create an issue," the source says. E! Online reports that Turner, who plays Sansa Stark in the HBO series, and Jonas posted the same picture of her ring on Instagram Sunday. "I said yes," she wrote on her page. "She said yes," he wrote. (Back in 2009, Kevin became the first of the brothers to get married.)
